TO WHOM ITMAYUONCERN:

f Be known that I, HENIWVN.' KING, of Adriamin the county of Lenawee, and State of Michigan, `have invented anew anduseful Improvement in Adjustable Jaws for Vises; and I do declare that the following is a true .and accuratedeseription thereof, referenceA being -had to the accompanying' drawings 'and to the letters of reference marked thereon, and makingapart of this specification.

Figure 1 is a side view. I

Figure 2 is a top view..

Figure 3 is a vertical sectional view; and

lThe same letters refer to like parts in eaeh view. The object of my invention is to so construct an adjustable vise-jaw, that bevelled articles, may be firmly held in anyposition required for work.- I ,y l V To aecomplish'this end, I`will now describen/1y invention as attached to ajaw of annordinary vise, and in such a manner that thoseskilled in the art can manufacture it. p y I l represents the stationary jaw of vise, and B the movable jaw. To the inner side of the jaw, B, I attach a metalV plate, (1 Through the jaw B and plate Cpasse's thebolt D, upon the Ainnerend of 'which is castthe ball E. Before v'thebolt' is passed through, as above described, the collar F is slipped over it, with a hole through it that ts over the ball, but notlarge enoughv for the ballto pass through it.A After the bolt is passed through the jaw' andl plate,- as described, the collar F is fastened in-any `suitable manner to the plateG, provided in the centre with eoncavity suin'eiently large for the ball'to play easily withinit. The plate `Gr is thenatt'aehed to a faceplate, II. Upon the top and at :either side of the collar tF, I attach, by propera'stenings, the adjustable stops I I I, which, when open, hold the face-plate II parallel with the face oi' thejstationary jaw A, By closing either ofthe side stops, the face-plate will assume a horizontally angular position, as may beldesired, and by `closing the upper stop, it willassumo a perpendieularly angular position -to the'stationary jaw A. The metal plate C is so constructed that it has a proJecting standard, J, upon the top o f which are fitted p the parts above described," `in such a manner as to allow the parts to work in the way referred .toholding them steady and in place at all times. I v v `My object in attaching the stops II I to the plate G, instead ofthe plate C, is so'asto be able, in attaching the whole `to aniron vise, to do away with thel plate C, and attach the whole 'to the movable jaw oi' the vise, riveting the standard J directly to thejaw of the vise. I I

What I claim as my invention, and desire to secure by Letters Patent, is-l y The combination ofthe stationary jaw A, the movable jaw theplate C, the bolt D,'the ball E,`th'e collarv F, the plate Gr, the faee-plate H, the adjustable stops I, and the projecting standard, when construct-ed, arranged,

and operating substantially as and for the purposes herein set forth. e
